"I do facial exercises from one of my favorite aestheticians, Nicola Joss, who basically has you sculpt your face from the inside out," Meghan Markle said to Birchbox in 2014.

She added: "I swear it works, as silly as you may feel. On the days I do it, my cheekbones and jawline are way more sculpted. There's a reason she is in high demand around awards season when every actress wants to look A-plus."

Facial exercising is the latest beauty trend to take off. This new concept claims to replicate the effects of a face-lift, but without the needle, using kneading movements to strengthen muscles, improve lymph flow, and boost circulation.

Joss posted several photos on Instagram of Markle, close friend Priyanka Chopra, and "Suits" co-star Sarah Rafferty during the royal wedding this weekend, suggesting she may have been responsible for their glowing skin.

The trend is spreading, and now famed New York department store Saks Fifth Avenue wants a slice of the action. The new beauty section at its flagship store in Midtown Manhattan, which opens on Tuesday, will include an outlet of the UK facial salon FaceGym.

Calling itself a "non-invasive workout," FaceGym claims to be another natural alternative to a face-lift - a way to tighten and tone the 40 muscles of the face using kneading movements with hands and technology.

"When a new face lifting procedure left me housebound, I decided it was time to act and create a non-invasive, zero-risk, face lifting solution that really works," founder Inge Theron writes on the company's website.

The signature, 30-minute facial, which will be offered at Saks, costs $70 and is described as an "all-around workout." There are other more expensive options, such as "Cryo Oxygen," during which customers are given a high-pressure shot of frozen carbon dioxide designed to plump up the skin and give you the Markle effect.

The new beauty department will open as part of a $250 million renovation of the store, which also includes a revamp of the main floor to focus on luxury goods and accessories and the opening of the legendary Parisian restaurant L'Avenue, Bloomberg reported.
